ITED STATES PATENT i WILLIAM J. HALSALL, OF GREENFIELD, INDIANA.

ROLLING-MILL.

To all whom it may concern: I

Be it known-that I, WILLIAM J. HALSALL, a citizen of the United States, residing at Greenfield, countyof Hancock, and State of Indiana, have invented certain new and useful. Improvements in Rolling-Mills, of which the following is a specification.

My invention relates to rolling mills and the object of my invention is to provide an improved rolling mill for reducing old railroad iron to bars of uniform cross section and subsequently shaping them into bars of cruciform cross section to be used as fence posts.

A further object of my invention is to provide a device as mentioned of such construction that old railroad iron may be reduced to bars of merchantable iron.

A further object of my invention is to provide means for adjusting rollers relative to each other to secure the maximum eiiiciency in the action of the rollers upon the material.

A further object of my invention is to providein a rolling mill means for adjust ing the rollers relative to each other and means for adjusting a portion of one-of the rollers with relation to the cooperating roller. 1

Other objects will appear hereinafter. I With these objects-in view my invention consists generally in a pair of coacting rollers provided with suitable bearings and having their peripheries shaped toreduce the railroad iron or old rails to-bars by successive passes between the same. 1 I

My invention further consists in a pair of rollers as mentionedarranged to reduce rails of various sizes to a uniform height preparatory to severing thesame into separate bars, means for scoring the web by a second pass, and meansfor severing theball and the flange portions or the ball portion only, by a third pass.

My invention further and more particularly consists in a rolling mill having the cooperating rollers as abovestatedwith the trunnions of the rollers mounted" inbear-. ings arranged in suitable housings and means on one of the housings for shifting one of the bearings to adjustthe respective rollerlongitudinally with relation to the cooperating roller. 7

My inventionfurther consists in a pair of superimposed cooperating 'rollers of the Specification of Letters Patent.

suitable housings,'means for shifting the bearings ofthe'lower roller to adjustsaid roller longitudinally with relation to the upper roller and means for adjusting the bearings for the journals of the upper roller to adjust the upper rollervertically with relation to the lower roller.

My invention further consists in a pair of rollers shaped with cooperating ribs and grooves for the purpose mentioned, means for shifting the rollers longitudinally with relation to each other to adjust certain of said grooves and ribs and means whereby certain portions of one of said rollers may be adjusted independently of the remaining portions. V

My invention further consists in a rolling mill comprising a pair of cooperating rollers and guides adjacent said rollers to prevent curling of the material, said guides comprising plates having apertures therein corresponding inshape to the spaces between the rollers.

Myinvention further consists in variousdetails of construction and arrangements of parts all as will be more fully described hereinafter and'particularly pointed out in the claims. U

My invention will be-more readily understood by reference to the accompanying drawings forming a part'of this specification and in which Figure 1 is a front elevationofa rolling mill. embodying my invention in its preferred form one of the housings and a portionof one of the rollers being illustrated in section, Fig. 2 is a side elevation of the same, Fig. 3 is a-detail section on the line w.a of Fig. 2, Fig. 4: is a similar section on the line y-y of Fig. 2, Figs. 5 and 6 are detailed views illustrating in elevation the guide plates for the material, Fig. 7 a

detail view illustrating the construction of H one end of one of the rollers, equipped with a shearing collar to be used for severing the flange from the web, Fig. 8 is a view similar to Fig. 4 illustrating a modified form of the adjusting device, and Fig. 9 is an elevation of a pair of rollers employed for shaping the bars formed from the rail into'bars of cruciform cross section for use as fence posts.

Referring now to the drawings, -1 and 2 Patented Sept. 15, 1914. Application filed November 8, 1913. Serial No. 799,836..

indicate a pair of superimposed roller spre vided with the trunnions 3-3 and 44 re spectively mountedin-bearing blocks 5 and 6. 7 indicates the-housings for the bear- ]ing blocksfi and 6 which'are preferably U- shaped in cross section as indicated in Figs. 3 and .4. The trunnionsor ournals 3 and 1 are provided with ribs 8 fitting within corresponding grooves "9- in the bearing blocks whereby the rollers are in fixed re lation longitudinally torsaid blocks, that is,

fthere is no free play longitudinally between the t'runnions and the bearings. The rollers V 1 1 and 2Ihave their peripheries shaped as at V 10 to compress the rails to a uniform'height by passing the same therethrough'after heat-' ing; asat 11 to score the web of the rail below-the ball when it is-desiredto, sever the ballonly fro'm the rail, and asfla tll Ito score the web adjacent both the hall and 'the'fiange when therail is to'be sheared into three pieces. To shear the ball from the web'javshe'a'ring edge 12-is formed on the roller 1 to cooperate with a shearingedge 12"on'th e'roller 2;". f"?

To insure aproper coctionof'the shear "1 ing edges -12; and 13 to secure the maximum efliciency' of :tllQfClBVlCQ, is one of the pmmary ob'ectszof my invention and to. this end I providefmeans for adjusting the lower roller having the shearing edge 12 long.i-.

, tudinallyiwith relationfto the upper roller having theShearing edge 12, and provide- [additional means for adjusting the edges 13 and 13 with relation .to'each otherr -;'To adjust the edges 12'and12I provide means for' adjusting one of the bearing L blocks 6 accordingly. A pair of set screws 7 face of one of the bearing blocks 6.

14i-14.are*threaded throughthe outer wall of the housing and bear against the outer See F ig," 4, Athird screw 15 passes loosely through a bore 16 in the outer wall of the housing and is threaded into the block 6. A collar 17 is formed on the screw 15 abutting the outer face of the housing and it is obvious that by means of the screws'l l' and 15 the position of the block 1'6'may be.

readily adjusted in the housing to shift the lower-roller 2 longitudinally with relation to the upper roller 1, thereby adjusting the relation of the edges 1212.

in position by a' set screw 6 threaded through the housing andlb'earing against the same; 7

Adjacent. the edge 12 of the roller 1, roller is reduced in diameter andfthreaded as at 18 and'uponthis portion 18isthreaded an auxiliary section 19. I provide two of the sections 19, one form as illustrated in Fig.1 and the other as shown in' Fig. 7. When it is desired to shear the ball only from theweb I use the form shown in Fig. 1; but should I desire to shear both the ball After the block 6 is properly adjusted it is heldfirmly and flange fromtherweb I employ fthe form T dation of the adjacent portion of the flange and web as is well understood. A'squared portion 20 is provided to facilitate turn:

ing the section 19 onthe threaded'portion 18, and it isobvious that by turning said section the relation of the edge 13 to the justed. Vasliers 21 of various-"thicknesses may be interposed between the'member 19 and the shouldered endsofthe roller 1 if: "preferred. f I 1 ,7

- 7 To adjust thedistance between the :rollers l and 2 when in operation soja's to regulate .the thickness of the: product,. I provide means, for vertically adjusting the bearing: blocks 5, This consistsjof a screw 22threads shownin Fig. 7; As shown inFig. 7 the].

In Fig; 9Ighave shown a pair'tr 305 and 31' provided with cooperating shaped ribs and gr0oves32 and 33 for shaping the:

bars passing from :the rollers .1.-and:2 into bars of cruciform cross section. "By-having the groove 33 of considerable depth and. the ribs 32, a-hi'gh class-finished article is produced without rough'or feather edges." ,1

a In Fig. '8 'I- ha've illustrated a; modified form; ofadjusting device adapted to be used with housings of the ordinary form, thatfis;

those not provided withuthe outerwall through which ,theflscrews '14: and. 15 are threaded; In said figure "7 indicates the 1 housing. :TSecuredqto the: housing adj acent the bearing;,block16' is a u-shaped-member -7v comprising a pair of arms??? embracing the: sides :of the housing and intermediate portion 7 The screws 14 are threadedthrough the portion '7-- of the member 7.: a
